NR 546 CU EXAM QUESTIONS AND DETAILED ANSWERS 2025 UPDATE. How does reviewing the genetic makeup of a client help guide the PMHNP in selecting medication for clients? - Correct Answer-Genetic testing can assist by providing more information on how clients may respond to certain psychotropic medications, as well as providing information on how a client may break down and metabolize medications based on the cytochrome P450 system. There may be an environmental exposure that turned a gene "on" that should have been "off" for one twin to develop schizophrenia and not the other . Both environmental and psychosocial stressors can impact mental health. Although twins may have identical genes, their gene expression may be different. Neuroscience - Correct Answer-is the study of the structure and function of the brain and is a field which is making great advancements (Pliszka, 2016). A strong foundational understanding of neuroscience and how the structure and function of the brain can result in mental health symptoms is necessary to treat mental illnesses. Some mental disorders such as Alzheimer's disease, schizophrenia, and major depressive disorder are thought to be a result of malformations or malfunctions within the brain. The psychiatric mental health nurse practitioner (PMHNP) must comprehend how medications impact the brain in order to safely and effectively prescribe psychotropic medications. Brain tissue - Correct Answer-is composed of gray and white matter. gray matter - Correct Answer-The cerebellum, cerebrum, brain stem, and the butterfly-shaped portion of the central spinal cord are comprised of gray matter which contains neural cell bodies, axon terminals, dendrites, and all nerve synapses. It is the working area of the brain and the focus of psychiatry and neurology. Gray matter - Correct Answer-associated with learning. Changes in the gray matter are linked to psychiatric diagnoses including Alzheimer's disease, schizophrenia, and major depressive disorder. White Matter - Correct Answer-contains nerve fibers that connect neurons from different regions into functional circuits. The myelin that coats neuronal axons is necessary for electrical impulse transmission. Think of the white matter as a transit system. If there are breaks in the system, then people cannot get to their destinations. Within the brain, these breaks affect neural communication, affecting behavior. Damage to the myelin can impair transmission which can impact not only sensory and motor function, but also cognition. White matter abnormalities are associated with autism and vascular dementia. The central sulcus separates which lobes? - Correct Answer-frontal lobe from parietal lobe Frontal lobe - Correct Answer-Associated with movement, intelligence, abstract thinking. etc. Broca's area - Correct Answer-Speech Temporal lobe - Correct Answer-Involves object identification and auditory signals Cerebellum - Correct Answer-coordination and balance Wernicke's area - Correct Answer-Speech comprehension occipital lobe - Correct Answer-Primary visual area parietal lobe - Correct Answer-Keeps us alert to what is going on around us Sensory Cortex - Correct Answer-Pain, heat, and other sensations motor cortex - Correct Answer-Movement Hippocampus - Correct Answer-Involved in both memory and anxiety Nucleus accumbens - Correct Answer-Involved in the reward process. Thalamus - Correct Answer-Involved in sensory organ and motor command processing Striatum - Correct Answer-Involved in complex motor actions, also links cognition to motor actions Limbic System - Correct Answer-This includes circuits that are associated with pleasure and reward, emotion and learning Basal ganglia - Correct Answer-A group of structures involved in voluntary motor movements Amygdala - Correct Answer-Involved in emotional regulation and perception of odors Corpus callosum - Correct Answer-Controls the communication between the two brain hemispheres white matter - Correct Answer-Contains nerve fibers that connect neurons from different regions into functional circuits Grey matter - Correct Answer-Contains nerve cells and dendrites Brain tissue - Correct Answer-Made up of grey matter and white matter What is the global burden of disease of mental health, neurological, and substance use disorders? - Correct Answer-30% How many children and adolescents are impacted by mental health disorders worldwide? - Correct Answer-20% How much does lost productivity related to anxiety and depression cost the global economy each - Correct Answer-$1 trillion USD The development of mental health conditions are linked to causes - Correct Answer-such as genetics, biochemical processes, environment, and lifestyle. Mental illness is common, and treatment often includes the use of psychotropic medications. When prescribing medications, the psychiatric mental health nurse practitioner (PMHNP) must consider each client's unique circumstances including, but not limited to their: - Correct Answer-symptoms age physical health previous response to treatment lifestyle Treatment for mental health conditions requires - Correct Answer-individualized care that incorporates the client's desires and goals. Which is the priority data used to determine a treatment plan for mental health disorders? - Correct Answer-client symptoms Adherence - Correct Answer-can be defined as persistence or compliance. Persistence is taking the medication over the intended time period. Compliance is taking the medication as prescribed. According to Dell'Osso et al. (2020), client, clinician, and structural factors all contribute to non-adherence. Client factors that contribute to nonadherence include - Correct Answer-concern about side effects, fear of addiction to medications, misunderstanding of expected outcomes. Clinician factors that contribute to nonadherence include - Correct Answer-lack of shared-decision making with the client, providing inadequate education about medications, and lack of follow up. Structural factors that contribute to nonadherence include - Correct Answer- medication access, medication cost, and stigma associated with mental illness. Informed Consent - Correct Answer-Clients have the right to receive enough information to make decisions about treatment. They must also be informed about potential risks associated with medications. Clients have the right to refuse treatment and cannot be forcibly medicated in non- emergencies. However, clients can be forcibly medicated if they are violent toward themselves or others and when less restrictive methods have failed. Compliance - Correct Answer-A court order may be issued for a client to receive treatment against their wishes if they are considered a danger to themselves or others.
